Solar irradiance has been universally acknowledged to be dominant by quasi-decadal variability, which has been adopted frequently to investigate its effect on climate decadal variability. As one major terrestrial energy source, solar-wind energy flux into Earth’s magnetosphere(ein) exhibits dramatic interannual variation, the effect of which on Earth’s climate, however, has not drawn much attention. Based on the einestimated by 3D magnetohydrodynamic simulations, we demonstrate a novelty that the annual mean eincan explain up to 25% total interannual variance of the northern-hemispheric temperature in the subsequent boreal winter. The concurrent anomalous atmospheric circulation resembles the positive phase of Arctic Oscillation/North Atlantic Oscillation. The warm anomalies in the tropic stratopause and tropopause induced by increased solar-wind–magnetosphere energy persist into the subsequent *** to the dominant change in the polar vortex and mid-latitude westerly in boreal winter, a ‘top-down’propagation of the stationary planetary wave emerges in the Northern Hemisphere and further influences the atmospheric circulation and climate.

Anthocyanin accumulation is a common phenomenon seen in plants under environmental stress. In this study,we identified a new allele of ROOT HAIR DEFECTIVE3（RHD3）showing an anthocyanin overaccumulation phenotype under nitrogen starvation conditions. It is known that ethylene negatively regulates light- and sucrose-induced anthocyanin biosynthesis. We hypothesized that RHD3 achieves its negative effect on anthocyanin biosynthesis via an ethylene-regulating pathway. In support of this, similar to rhd3 mutants, the Arabidopsis ethylene signaling mutants etr1, ein2, and ein3/eil1 showed an anthocyanin overaccumulation phenotype under nitrogen starvation conditions. The ethylene precursor ACC strongly suppressed anthocyanin accumulation, dependent on ETR1, ein2, ein3/EIL1, and, partially, RHD3. In addition,inactivating RHD3 partially reversed the suppressive effect of ETO1 inactivation-evoked endogenous ethylene production on anthocyanin accumulation. The expression of nitrogen starvation-induced anthocyanin biosynthesis genes was negatively regulated by RHD3, but ethylene response genes were Researchpositively regulated by RHD3. Wild-type seedlings overexpressing RHD3 showed similar phenotypes to rhd3 mutants,indicating the existence of a fine-tuned relationship between gene expression and function. RHD3 was initially identified as a gene involved in root hair development. This study uncovered a new physiological function of RHD3 in nitrogen starvationinduced anthocyanin accumulation and ethylene homeostasis.

The phytohormones ethylene and salicylic acid(SA) have long been known to promote senescence, but their interplay during this process remains elusive. Here we report the synergistic effects of ethylene and SA on promoting leaf senescence in Arabidopsis. ein3, a key transcription factor of ethylene signaling, physically interacted with the core SA signaling regulator NPR1 in senescing leaves. ein3 and NPR1 synergistically promoted the expression of the senescence-associated genes ORE1 and *** senescence phenotype was more delayed for the ein3 eil1 npr1 triple mutant than ein3 eil1 or npr1 with ethylene or/and SA treatment. NPR1-promoted leaf senescence may depend on functional ein3/EIL1.
